INTRODUCTION

There are four different sections of the board.

Section 1 is a differential input, differential output amplifier configuration using a dual-amplifier pin out. Section 2 is a two op-amp, differential amplifier using a dual-amplifier pin out. Sections 3 and 4 are identical amplifier circuits although they have different component designators for their
components . These can be configured for either inverting gain or non-inverting gain configurations. Sections 3 and 4 use the single-amplifier pin out.

The following table provides a brief summary of features for the op-amps included with the CDB30xx board.

CIRCUIT 1 - DIFFERENTIAL INPUT / DIFFERENTIAL OUTPUT

Circuit 1 is a differential input / differential output amplifier. This circuit is commonly used to amplify the differential signal from a bridge transducer, such as a load cell. The amplified differential output signal is then input into an A/D converter that has a fully differential input. For narrowband signals below 2 kHz, the CS3002 dual amplifier is a good choice for this amplifier configuration because it provides low noise and can be configured for gains as high as 2000X. Gain is set by the equation,

R13 R19 Rx
where Rx is R15, R16, or R17, selected by a jumper connection.
